Try your first PAMI program

$ python

# first import pami 
from PAMI.frequentPattern.basic import FPGrowth as alg
fileURL = "https://u-aizu.ac.jp/~udayrage/datasets/transactionalDatabases/Transactional_T10I4D100K.csv"
minSup=300
obj = alg.FPGrowth(iFile=fileURL, minSup=minSup, sep='\t')
#obj.mine()  #deprecated
obj.mine()
obj.save('frequentPatternsAtMinSupCount300.txt')
frequentPatternsDF= obj.getPatternsAsDataFrame()
print('Total No of patterns: ' + str(len(frequentPatternsDF))) #print the total number of patterns
print('Runtime: ' + str(obj.getRuntime())) #measure the runtime
print('Memory (RSS): ' + str(obj.getMemoryRSS()))
print('Memory (USS): ' + str(obj.getMemoryUSS()))

Output:
Frequent patterns were generated successfully using frequentPatternGrowth algorithm
Total No of patterns: 4540
Runtime: 8.749667644500732
Memory (RSS): 522911744
Memory (USS): 475353088

Evaluation:

1. we compared three different Python libraries such as PAMI, mlxtend and efficient-apriori for Apriori.
2. (Transactional_T10I4D100K.csv)is a transactional database downloaded from PAMI and used as an input file for all libraries.
3. Minimum support values and seperator are also same.

• The performance of the Apriori algorithm is shown in the graphical results below:

1. Comparing the Patterns Generated by different Python libraries for the Apriori algorithm:

   

2. Evaluating the Runtime of the Apriori algorithm across different Python libraries:

   

3. Comparing the Memory Consumption of the Apriori algorithm across different Python libraries:

   

For more information, we have uploaded the evaluation file in two formats:

• One ipynb file format, please check it here. Evaluation File ipynb
• Two pdf file format, check here. Evaluation File Pdf

Background

The idea and motivation to develop PAMI was from Kitsuregawa Lab at the University of Tokyo. Work on PAMI started at University of Aizu in 2020 and has been under active development since then.
